Free, no account
Throw a syllabus at it.
Pick one of your course outlines. In about a minute you'll see every graded item with its date and weight, the key deadlines buried on page nine, and the rules that decide what happens when something goes wrong. Then you can decide whether it's worth an account.
No email, no card. You'll see the whole result before deciding anything.
Scans are fine
No text layer? It reads the pages as images.
Nothing is shared
Your document is read to build your course record, and that's it.
It flags its guesses
Anything worked out from “Week 6” is marked so you can check it.
Curious how it does it? How it works. Comparing options? See it against Google Calendar, Notion and your LMS.
